The research article entitled ‘Association between yogurt and dietary supplements containing probiotic consumption with sleep disturbance in US adults: Results from NHANES, 2009-2018’ explores the relationship between consumption of yogurt and dietary supplements containing probiotics and sleep disturbance in US adults.
Sleep disorders are a common public health problem, affecting a large proportion of the world's population. The gut microbiome, which plays a crucial role in brain homeostasis via the microbiota-gut-brain axis, is increasingly recognised for its involvement in sleep disorders. Probiotics, as living micro-organisms found in fermented dairy products such as yoghurt, have been shown to have potential beneficial effects on sleep quality.
This study evaluated the association between consumption of yoghurt and probiotic supplements and the prevalence of sleep disorders in a large cohort of American adults.
49,693 adult participants from the National Health and Nutrition Examination Survey (NHANES) were included in this study, between 2009 and 2018. After excluding participants under the age of 18 and those with missing data on yoghurt consumption, probiotic consumption or sleep disorders, the final sample comprised 24,820 participants. Consumption of yoghurt and probiotic supplements was assessed using a food questionnaire, while sleep disorders were measured using a questionnaire on sleep disorders and sleep duration.
Of the 24,820 participants, 14.24% consumed yoghurt and/or supplements containing probiotics, i.e. 3,535 participants. The prevalence of sleep disorders in this population was 16.22%, and only 53.51% of participants achieved the recommended sleep duration (7-9 hours per night). Weighted logistic regression models showed that consumption of probiotics was associated with a significant reduction in the risk of sleep disorders. This protective association was particularly notable in men, non-Hispanic whites and individuals with a normal BMI.
However, this effect was less significant in women and obese individuals. This suggests that the response to probiotics may vary according to sex, race and weight status. The results of this study suggested a positive association between probiotic consumption and improved sleep quality.
The study concludes that consumption of yoghurt and supplements containing probiotics is associated with a reduced risk of sleep disorders in American adults. The results underline the importance of probiotics as a public health strategy for improving sleep quality, with a potentially greater impact in specific populations. Future research should explore the underlying mechanisms and efficacy of different probiotic strains on sleep.
